Abstract

To provide a catalyst converter device for purifying exhaust gas capable of improving engine performance and exhaust gas purification performance while improving productivity. [Solution to Problem] The thickness of a retaining mat 81 is set so that the apparent density of the retaining mat 81 during assembling becomes 0.25 g/cm3 or more and less than 0.51 g/cm3 and the outside diameter Dl of a catalyst retainer 80 is set according to interference of the retaining mat in passing through a press-in tool 105 and interference of the retaining mat after being pressed-in to a retaining tube 82, the retaining mat 81 is formed of a non-expandable inorganic fiber sheet, a pressing force F that moves the catalyst retainer 80 in the axial direction with respect to the retaining tube 82 while the catalyst converter device 63 is used is obtained, and the length L2 along the longitudinal direction of the catalyst retainer 80 in the retaining mat 81 wound around the catalyst retainer 80 is set longer than the winding diameter Dl of the retaining mat 81 around the catalyst retainer 80 so that a retaining force R greater than the pressing force F can be secured.
